Improve tray icon visibility: Claude orange, full opacity, larger size

Browse Source 
Starburst was nearly invisible at tray icon size due to white color at
50% alpha on a 128px canvas. Now renders in Claude brand orange (#E07B53)
at full opacity on a 256px canvas with proportionally scaled geometry.
